Joomla .htaccess，需要重定向整个网站（除了单个 URL）

Question

在 Joomla 网站中，我尝试将所有 URL 从旧域重定向到新域，除了单个 URL

https://olddomain.com/subfolder/eliminar-cuenta.html

为此，我在

.htaccess

中写下了这条规则

RewriteCond %{REQUEST_URI} !^/subfolder/eliminar-cuenta.html
RewriteRule ^(.*)$ https://www.newsite.com.ar/ [R=301,L]

这是整个

.htaccess

## Mod_rewrite in use.

RewriteEngine On

## Begin - Rewrite rules to block out some common exploits.
# If you experience problems on your site then comment out the operations listed
# below by adding a # to the beginning of the line.
# This attempts to block the most common type of exploit `attempts` on Joomla!
#
# Block any script trying to base64_encode data within the URL.
RewriteCond %{QUERY_STRING} base64_encode[^(]*\([^)]*\) [OR]
# Block any script that includes a <script> tag in URL.
RewriteCond %{QUERY_STRING} (<|%3C)([^s]*s)+cript.*(>|%3E) [NC,OR]
# Block any script trying to set a PHP GLOBALS variable via URL.
RewriteCond %{QUERY_STRING} GLOBALS(=|\[|\%[0-9A-Z]{0,2}) [OR]
# Block any script trying to modify a _REQUEST variable via URL.
RewriteCond %{QUERY_STRING} _REQUEST(=|\[|\%[0-9A-Z]{0,2})
# Return 403 Forbidden header and show the content of the root home page
RewriteRule .* index.php [F]
#
## End - Rewrite rules to block out some common exploits.

## Begin - Custom redirects
#
# If you need to redirect some pages, or set a canonical non-www to
# www redirect (or vice versa), place that code here. Ensure those
# redirects use the correct RewriteRule syntax and the [R=301,L] flags.
#

RewriteCond %{REQUEST_URI} !^/subfolder/eliminar-cuenta.html
RewriteRule ^(.*)$ https://www.newsite.com.ar/ [R=301,L]

## End - Custom redirects

##
# Uncomment the following line if your webserver's URL
# is not directly related to physical file paths.
# Update Your Joomla! Directory (just / for root).
##

RewriteBase /subfolder

## Begin - Joomla! core SEF Section.
#
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
#
# If the requested path and file is not /index.php and the request
# has not already been internally rewritten to the index.php script
RewriteCond %{REQUEST_URI} !^/index\.php
# and the requested path and file doesn't directly match a physical file
RewriteCond %{REQUEST_FILENAME} !-f
# and the requested path and file doesn't directly match a physical folder
RewriteCond %{REQUEST_FILENAME} !-d
# internally rewrite the request to the index.php script
RewriteRule .* index.php [L]
#
## End - Joomla! core SEF Section.

但是 URL

https://olddomain.com/subfolder/eliminar-cuenta.html

不断重定向到新域。

有什么想法吗？

Answer 1

问题在于 Joomla 前端控制器模式将请求重写为

index.php

，并且在重写引擎的第二次传递期间，URL 不再是

/subfolder/eliminar-cuenta.html

，因此发生了重定向。

您需要确保重定向规则仅适用于初始请求，而不适用于重写的请求。

例如：

RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteRule !^subfolder/eliminar-cuenta\.html$ https://www.newsite.com.ar/ [R=301,L]

对

REDIRECT_STATUS

环境变量的检查确保我们只测试初始请求，而不测试重写的请求（当

REDIRECT_STATUS

非空时）。

无需单独的 条件 来测试 single URL，因为可以在

RewriteRule

指令本身中进行检查。

或者，您可以更改“Joomla！核心 SEF 部分”中最后一条规则的

L

标志。 （即

RewriteRule .* index.php [L]

）使用

END

代替。这会停止所有进一步的重写，从而防止重写引擎进行第二次重写。 （

L

标志只是停止当前传递。）这需要 Apache 2.4+。但是，如果这是类似 WordPress 的内容，则手动编辑本节中的代码可能是不明智的。

在测试之前，您需要清除浏览器缓存（可能还有中间缓存），因为错误的 301（永久）重定向将被浏览器缓存。首先使用 302（临时）重定向进行测试以避免这些缓存问题。

并且，如果此 URL（即页面）链接到其他本地资产（CSS、JS、图像等），那么您也需要允许访问这些资产（为其创建例外），否则它们将被重定向，以及与其他所有 URL 一起使用。

旁白： 通过将所有内容重定向到新网站的“主页”，它们将被 Google 视为软 404（并且可能会让用户感到困惑），因此这不太可能具有您可能期望的 SEO 优势。
